Shock absorber rubber
A rubber shock damper fitted in the clutch drive assembly of the primary transmission to cushion drivetrain shock.
This is the shock absorber rubber that lives in the primary transmission and clutch drive on the triples, per the parts book figure it appears in. It's one of the small rubber dampers fitted into the clutch drive assembly to cushion the shock of drive engagement rather than transmitting it straight through the gear train.

Our catalog record for 57-5001 shows it in the primary transmission and oil pump drive figure with a single appearance in the 1974 listings. We don't have more detail on it beyond that, so if you're sourcing this for a rebuild, confirm which clutch drive assembly your bike uses before ordering.
These rubbers wear and take a compression set over time, and a tired one can show up as extra drivetrain lash or clutch clatter, but that's a general point about the part class, not a specific claim about your machine.
Sorry if we got something wrong here. If you think this information isn't correct, .
